Abstract
The utility model discloses a gas decomposed constituent measurement gas chamber, comprising a gas inlet and a gas outlet, wherein an inner cavity is divided into a gas inlet cavity, a diversion cavity and a gas outlet cavity from the gas inlet to the gas outlet and the number of the diversion cavity is many and the inlet of each diversion cavity is communicated with the gas inlet cavity and the outlet of each diversion cavity is connected with the gas outlet cavity. While in use, the gas decomposed constituent measurement gas chamber prevents mutual interference of various constituent gases in the measurement process and the temperature of the gas to be measured is controlled to make the temperature of the gas to be measured constant while measuring, therefore the accuracy and consistency of the measurement result can be increased.
Description
Technical field
The utility model relates to a kind of electrical equipment decomposes component content with minimum gas such as the various fluorides of sulfur hexafluoride (SF6) gas, oxides decomposing gas component measurement air chamber that is used for measuring.
Background technology
General electrical equipment adopts sulfur hexafluoride gas to insulate, in when, in the electrical equipment insulation fault taking place when, discharge or overheatedly will make sulfur hexafluoride gas generation decomposition reaction, because its decomposition reaction is very complicated, also there is certain dispute in domestic and international research to its course of reaction at present, but most result of study comprises the analysis and research to a large amount of accident equipment and all shows, because shelf depreciation and the caused reaction of local overheating generate several more stable sulfur hexafluoride decomposition gases the most at last, these gases mainly comprise SOF
2, SO
2, CF
4, H
2S, HF and CO that is to say that the variation of above-mentioned gas composition will reflect shelf depreciation and insulation situation of change in the electrical equipment, and can provide the equipment operation early warning in view of the above.The measurement of the content of industry sulfur hexafluoride decomposition gas is at present carried out in measuring air chamber.Existing measurement air chamber is tubular body or rectangular box, the left end of tubular body or rectangular box has air intake opening, right-hand member has the gas outlet, the inwall that air intake opening is provided with flow control valve measurement air chamber is connected with metering circuit, directly connect various galvanochemistry gas sensors or semiconductor gas sensor on the metering circuit, metering circuit is connected with the external world by connecting lead again.During use, the sulfur hexafluoride gas of electrical equipment enters by the air intake opening of measuring air chamber, flows out from the gas outlet of measuring air chamber again, and various galvanochemistry gas sensors record the content of wherein each kind of decomposing gas component when sulfur hexafluoride gas flows through.There is following point in this measurement air chamber: 1, this measurement air chamber is that the content to component gases is measured in same cavity, therefore exists the problem that various component gases are crosstalked after measuring process or measurement mutually, causes measurement result inaccurate.When 2, utilizing this measurement air chamber to advance to measure, because the temperature of tested gas is very big with environmental change, and gas sensor or electrochemical sensor are very sensitive to the temperature of tested gas, measurement result to each component in the gas need be carried out temperature compensation, and the mode of compensation do not have standard can foundation, cause the measurement result that after compensation, draws inaccurate.
The utility model content
The purpose of this utility model provides a kind of decomposing gas component of avoiding various tested gases to crosstalk mutually in measuring process and measures air chamber, thereby can improve the accuracy to the gas composition measurement result.
For achieving the above object, the utility model is taked following design proposal:
A kind of decomposing gas component is measured air chamber, it has air intake opening and gas outlet, it is characterized in that, its inner chamber is divided into inlet chamber, diversion cavity and outlet chamber from described air intake opening successively between the described gas outlet, the quantity of described diversion cavity is a plurality of, the import of each diversion cavity is connected with described inlet chamber, and the outlet of each diversion cavity is connected with described outlet chamber.
The quantity of described diversion cavity is 2 ~ 6.
The outer wall of described inlet chamber is provided with semiconductor chilling plate.
The air intake opening of described inlet chamber is provided with flow control valve.
The utility model has the advantages that:
1, the utility model decomposing gas component is measured air chamber, it has air intake opening and gas outlet, its inner chamber from air intake opening to being divided into inlet chamber, diversion cavity and outlet chamber between the gas outlet successively, the quantity of diversion cavity is a plurality of, the import of each diversion cavity is connected with inlet chamber, and the outlet of each diversion cavity is connected with outlet chamber.Before the use, be provided with a kind of galvanochemistry gas sensor or semiconductor gas sensor in each diversion cavity.During use, sulfur hexafluoride gas to be measured enters from the air intake opening of measuring air chamber, shunting enters each diversion cavity behind inlet chamber, gas is recorded the content of decomposing gas component by each galvanochemistry gas sensor or semiconductor gas sensor in each diversion cavity, the gas after measured is discharged from the gas outlet through outlet chamber again.Because the gas in each diversion cavity can not crosstalked mutually in measuring process, therefore can improve the accuracy of measurement result.
2, the utility model decomposing gas component is measured air chamber, according to decomposing gas component quantity to be measured the quantity of diversion cavity is made as 2 ~ 6.
3, the utility model decomposing gas component is measured air chamber, and wherein the outer wall of inlet chamber is provided with semiconductor chilling plate, and so that the gas temperature in the inlet chamber is controlled at 20 ℃, error is ± 1 ℃.The result who records like this need not to carry out temperature compensation, has further improved the accuracy and the consistance of measurement result.
4, the utility model decomposing gas component is measured air chamber, wherein the air intake opening of inlet chamber is provided with flow control valve, make the gas flow that enters the measurement air chamber be controlled at constant scope, by sensor measurement the time, can satisfy sensor to tested gas flow detection requirement so that enter the tested gas of measuring air chamber.
